Columbine excoriates Buckley, I'm willing to cut him a little more slack because not only do attitudes change, he also later said that had he been black in South Africa, he saw little choice but to join the ANC. Along those lines, Elf tosses off a Buckley quote that I think both addresses Columbine's complaint and my respect:

Conservatives pride themselves on resisting change, which is as it should be. But intelligent deference to tradition and stability can evolve into intellectual sloth and moral fanaticism, as when conservatives simply decline to look up from dogma because the effort to raise their heads and reconsider is too great.
